Nostalrius Begins - Quality wow vanilla realm (1.12)

We have been actively recruiting for our guild and just yesterday, we experienced quite a few users getting the invite, accepting the invite, and not actually being able to join the guild.

Upon attempting to re-invite the user our officers would see the message
"[name] has already been invited to join a guild."

If the invitee stayed logged in, the same message would occur even hours after the original invite attempt.
After asking the user to close their game client and log back in, it would repeat the same issue.

Any suggestions or this is a new bug I am reporting?

Thank you.

Only thing that comes to mind is, is there already 321 people in your guild? if so that would be the issue as you are capped.

Ahh, that makes sense. We have quite a few that haven't been on in a few weeks. We'll purge and try again.

Thank you Diametra.
